What is a canonical tag? A canonical tag is used as a signal to search engines that the nominated version of a URL is the version you want them to index and return in their results. A canonical tag (aka “rel canonical”) is a way of telling search engines that a specific URL represents the...

Closing the circle – Google acquisitions & the race to antitrust

With Facebook hogging most of the headlines over the last few months, Google has been quietly shoring up its assets and getting its ducks in a row. Facing a $5 billion fine by EU regulators for breaking antitrust laws with the Android locked-in ecosystem, the former-search provider has broken its own record for the highest...

The Generic Sensor API

Today’s devices pack in a vast array of sensors that gather data about the device and the world around it. For web applications, access to these sensors has grown over time through the addition to the browser of various sensor APIs such as the Geolocation API, and the DeviceOrientation Events API. Such APIs have been...

Google’s “Speed Update”: Page speed is important, but content is king

Google just rolled out a mobile “Speed Update” that affects mobile search rankings. You might be wondering what that means for you. What is the “Speed Update”? Page speed is now a ranking factor for mobile pages. Faster pages will rank higher. Everything else being equal, the faster of two pages will rank higher in...

Mobile-first index: How will it affect you?

Google’s mobile-first index is rolling out. If you’ve signed up to Google’s Search Console / Webmaster Tools you might already have received a notification “Mobile-first indexing enabled” for http://your-site.com. If you haven’t received the notification, you probably will soon. So, what does it mean? What is the mobile-first index? It’s a mobile-centric re-organisation of Google’s...

Momemtum for PWAs builds relentlessly

With two major developer conferences just behind us it’s worth reviewing where we are with PWAs. Microsoft added further momentum to PWAs at Build 2018 by detailing just how rich the support for PWAs will be. They aren’t doing this in half measures: A dedicated installation shortcurt from the Edge address bar Optional chromeless mode...

Surveillance capitalism is killing the web

As GDPR rolled into town, we spotted some odd examples of how companies and news websites are dealing with their newly enforced responsibilities. Instead of submitting to the spirit of the whole exercise, many high-value sites chose to segment their traffic into EU v Non-EU, and provide the former with a stripped down, minimal version...

PWA Minimus: A minimal PWA checklist

Now that Progressive Web Apps (PWAs) are supported on all major browsers, and are becoming first-class installable citizens on mobile and desktop platforms alike, and with the launch of Google’s PWA .app domain, we thought it would be useful to outline a PWA checklist to meet the minimum requirements of a PWA. The result is...

The HTML5 Pointer Events API: Combining touch, mouse, and pen

The Pointer Events API is an HTML5 specification that combines touch, mouse, pen and other inputs into a single unified API. It is less well supported than the Touch Events API, although support is growing, with all the major browsers working on an implementation, except for Apple's Safari. There's a colorful background to how the current state of browser support for this API came to be which we covered previously on mobiForge, but in this article we'll just look at its usage...

Webviews and User-Agent strings

Much is made of the comparative times spent browsing the web vs engaging with native apps in the apps vs web debate. An often overlooked part of the discussion is that when engaged with a native app some portion of this time is spent actually on the web, via a webview. We'll get to what a webview is in a minute, but for now, what this means is that although the user is in an app, he or she is effectively browsing the web...

The Oxymoron of Mobile Privacy

Introduction There could hardly be a more perfect privacy invasion machine than today's smartphone. It's with you at all times, it knows precisely where you are, it can see and hear you and it knows exactly what you are doing much of the time. If data is the pollution of the digital age then your smartphone is an overweight 1970's V8 gas guzzler with asbestos brake pads, a leaky freon-charged AC system, burning leaded fuel as it barrels down the highway: you are silently spewing out reams of potentially harmful data all day, every day...

HTML5 for the Mobile Web: Touch Events

With the widespread adoption of touchscreen devices, HTML5 brings to the table, among many other things, a set of touch-based interaction events. Mouse-based events such as hover, mouse in, mouse out etc. aren’t able to adequately capture the range of interactions possible via touchscreen, so touch events are a welcome and necessary addition to the web developer's toolbox. Use cases for the touch events API include gesture recognition, multi-touch, drag and drop, and any other touch-based interfaces...

HTML5 for the Mobile Web: Device Orientation Events

In this third article in our series on HTML5 for the mobile web, we take a look at the Device Orientation API. This API provides information about the orientation and movement of a device. Information comes from the positional sensors such as compasses, gyroscopes and accelerometers. Via this API, a web app can access and make use of information about how a device is physically oriented in space. Use cases include game control based on device tilting, and mapping where a map is correctly aligned with the world based on the device orientation data...

HTML5 for the Mobile Web – a guide to the Geolocation API

In this second article in our series on HTML5 for mobile web (first part here), we cover the Geolocation API. For mobile users, location-based services are hugely compelling. Long the holy grail of mobile applications, and something of a missed opportunity for service providers, the addition of location-awareness to mobile apps has made for some very exciting use cases...
